cmd: Add pause command
This command is being introduced with the goal of allowing user-friendly
"generic use case" U-Boot builds to pause until user input under some
situations.
The main use case would be when a boot failure happens, to pause until
the user has had time to acknowledge the current state.
Tested using:
make && ./u-boot -v -T -c 'ut lib lib_test_hush_pause'
